6 Claims.

, This invention relates generally to casement construction and more particularly to window casement construction using metal fram elements.

Among the objects of the present invention lies the provision of window casement construction facilitating the assembly of vertical and/or horizontal muntins with the surrounding sash elements or frame.

Another object herein lies in the provision of a novel connecting element by the use of which metal window easements may be quickly and conveniently manufactured in large scale at low cost, so as to enjoy a consequent wide distribution and use.

Another object of the present invention lies in the provision of simplified assembly of the muntins to the sash frame without the use of any special tools or skill so that 'peening of tenons, riveting or welding, commonly used, are obviated.

Another object herein lies in the provision of construction of the class described wherein the integration ofthe parts provides a sturdy window casement which is sufficiently rigid for the purpose intended and yet which for the purposes of repair or otherwise, may be disassembled.

A feature of the invention lies in the fact that since muntins may be installed at any desired position along the length of the sash frame members by merely drilling a single hole at the point of connection of the muntin with the sashframe member, the window arrangement can be altered atthe installation location to accommodate for vational view of the juncture of one of the horizontal muntins of Figure 3 with the left hand vertical sash frame elements. i

t Figure 2 is a fragmentary vertical sectional view as seen from the plane 2-,-2 on Figure 1. i Figure 3, is a front elevational view of a window casementshowing an embodiment of the inventiom i v cal side sash frame elements H and I2, a top sash frame element [3 and a bottom sash frame element l 4. Secured to the vertical frame elements [I and I2 are horizontal muntins l5 and 16. While we have shown only two horizontal muntins l5 and I6, obviously where desired any suitable number may be used, and while we have shown them to be horizontally arranged, where.

desired they may be vertically arranged. The present invention relates. primarily to a novel means and manner of assembling the muntins to the frame element.

The frame element II and the frame element H. are substantially identical except that one is arranged in a left hand position while the other is arranged in a right hand position. The frame element I l includes a front member l1 having an inner edge 18 and an outer edge I9. Projecting rearwardly from the outer edge [9 is a rib 20. The element ll also includesa rear member 2| having an inner edge 22 and an outer edge 23.. Projecting forwardly from the edge 22 is the looking flange 24. The front member I! and the rear member 2| are connected in spaced and parallel relationship by the inner and outer Webs 25 and 26, respectively which are also spaced and parallel and arranged substantially at right angles to the members ll] and 2|. The outer Web 26, at the forward edge thereof, connects with the rear surface 28 of the front member I! while the rear edge of the web 26 connects with the outer edge 23 of the rear member 21. The Web 25 at the forward edge thereof is connected to the surface 28 of the front member il inwardly of the edge l8 so that the edge [8 projects to form a lip. The webs 25 and 26 are provided with orifices 29 and 38 of uniform and predetermined diameter. The orifices 29 and 30 are coaxially aligned.

The left end of the muntin 15 has a normal edge or terminal 32 which is substantially at right angles to the length ofsaid muntins. Ifhe muntin l5 has a body 33, upper and lower vertical front flanges 3 4' and 35, upper and lower vertical rear flanges 36 and 31 and upper and'lower horizontal rear flanges 38 and 39. The front flanges 34 and 35 and the rear flanges-36 and 31 are spaced and parallel and preferably perpendicular with respect to the body 33. The rear flanges 38 and 39 are preferably spaced and parallel to each other and the body 33. The terminal edge 32 is provided with a notch 40 having spaced and parallel side walls M and 42 and an inner wall 43 preferably parallel to the edge 32.

' The flanges 34and 35 preferably extend the complete length of the body 33 while the rear flanges 36 and 31 stop short of the terminal edge 32 a distance substantially equal to or slightly greater than the distance between the outer face 44 of the inner web 25 and the outer surface 45 of the locking flange 24. The body 33 is provided with a locking indentation 46 having a forward wall 41, an inner wall 48 and an outer wall 49. The forward wall 41 is preferably spaced and parallel with the edge portion 50 of the body 33 and is spaced therefrom a distance substantially equal to the distance between the surface I of the locking flange 24 andthe forward surface 52 of 4 n be utilized on the right hand end of the muntin I5 or on upper and lower ends of vertically arranged muntins. Where it is desired to remove a muntin for repair purposes or otherwise it becomes necessary only to exert'suflicient pressure outwardly of the device In upon the inner tips of the bifurcated legs of the shank 55. When the connecting element is fully seated, upward and downward movements of the muntin I5 are prevented by the shank 55; movement of the muntin rearwardly or'outwardly of the device II] is prevented by the abutment of the edge 50 and wall 41, and the. terminal edge 32 against the vented by the wall 4 I.

59 (see Figure 4). The head has a plurality of V teeth 63 which are spaced and parallel to each other and extend around the head 54 parallel to the longitudinal axis of the connecting element 53. The tip circle of the teeth60 is of greater diameter than the diameters of the orifices 29 and 33 sorthat the lands of said teeth may cut into the borders of the orifices 29 and 30 to become frictionallysecured against movement in a longitudi nal direction with respect to the connecting element. Rotation of the head is prevented by the teeth 6D cutting their own grooves in the borders of the orifices 29 and 30,

The assembly of the device is a simple and convenient matter. The distance between the edge 58 and the forward surface "(SI of the flanges 34 and is less than the distance between the innor surface 52 and the rear surface 62 of the lip I8 by an'amount equal to the distance which the locking flange 24 projects forwardly from the surface 52. Thisenablesthe horizontal muntin I5 to be brought in a left hand direction as viewed in Figure '6, for example, only the edge 32 meets the outer face 44 of the inner web 25, whereupon the muntin I5 may be moved rearwardly until the surface 50 contacts the surface 52. The body 33 is aligned so that its longitudinal axis is in substantial alignment with the axes of the orifices 29 and 36. Next, the. connecting element is inserted through the orifices 3i) and 23 so that the chamfered edges 58 and 59 engage the upper and lower edges of the inner wall 43. Following this suitable force is applied upon the surface 63 of the head 54 in an axial direction so as to force the surfaces 56 and 5'! to engage the upper and lower surfaces respectively of the body 33. Thelength of the head 54 is preferably such that when fully j seated the surface 64 of the head 54 abuts against ,responding construction and engagements may Glazing of the finished casement may be performed in any usual mannenas for example, by the use of putty. a

We wish it to be understood that we do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.
